To all whom it may c ncern:

Be it known that I, FRED A. RUMNEY, a

citizen of the United States, residing at,

Somerville, in the county of MiddleseX and Stateof Massachusetts, haveinvented certain Improvements in EyeletingMachines, of which thefollowingdescription, in con-' nection with the accompanying drawings,is a specification,"like reference'characters on y the drawingsindicating like parts in the several figures. I

" This invention relates to improvements 1n eyeleting machlnes, and morepart cu larly to improvements in eyeleting machines of the typedisclosed in Letters Patent of the United States, September 14, 1909,cation of George Goddu,

No. 934,066, dated tomachinesof other types or machines for settingother forms of fasteners, such, for lnstance as studs or rlvets.

An object of the present invention is to provide a simple and effectivearrangement for retracting the punches and setting dies connected with aretracting lever which is actuated by a sprlng pressed plunger forretracting its respective punch or set and maintaining it out ofengagement with the work. The compression springs for actu- 'atlng eachof the plungers are lncased 1n a portion of the feed frame and are thushidden from inspection. It has been found that these compression springsare liable to.

break or become slow in action from other causes and that on account oftheir concealed position the operator neglects to replace them untiltheir complete failure results in a catastrophe to'the machine. The

present invention, however, contemplates a 7 novel construction and"arrangement ofparts which obviates the difliculties above discussed, andat the same timesimplifies the general organization of the machine andthereby reduces its cost.

To this.end,"an important feature- 0f the invention consists inproviding single de- 1 vices for retracting both punches and both setsand in so locating such devices that they may be, at all times, readilyaccessible and .open to inspection. Preferably the punchSpecification-of Letters Patent.

invention contemplates an arrangement of the anvil plate and work restsuch that the acting surfaces of both are rendered substantiallycontinuous, the occurrence of a space between them into which a part ofthe work could enter and become caught. As herein shown this'isaccomplished by mounting on one of said thereby preventing members auard late which-is arran ed to slide freely in a slot formed the othermember. Preferably the guard plate may be mounted on the anvil'plate' bymeans of a long reduced shankand this construction the upsettin dies andcutting block may be retained in the anvil by having the shank passedthrough. them.

Setting devices or sets have been usually constructed of one piece ofstock shaped to set the desired eyelets and uniformly temperedthroughout. The present invention, however, contemplates the provisionof a setting device having a short detachable and replaceable portion inwhich the die proper is formed, the die portion being shaped to vfitlike a. cap over the end of the body portion of the setting device. Thisconstruction is advantageous in that the die itself may be formed ofhardened steel While the remaining portion of the setting device may beleft softer and consequently less brittle. The setting device may alsobe renewed at much less expense than formerly by merely replacing theportion in which the die is formed.

The features and advantages above set forth and others incident to theinvention will be best understood and appreciated in connection with thefollowing description taken in connection with the accompanying drawingsin which,

Figure 1 is a view in elevation of the punching, setting and work uidingportions of an eyeleting machine embodying the present invention; Fig. 2is a plan view l of the guide plate and anvil plate.

The machine shown in the drawings, like the machine of said patent, isorganized and arranged to punch two holes in the opposite sides of theupper of a shoe and then to set two eyelets in those holes and to feedthe work.

The principal features of the present invention, as already pointed out,reside in certain improvements in the various parts of this machine.Before proceeding to a detailed description of these parts it will beconvenient to refer to the general mode of operation and relativearrangement of the machine. c The machine shown in the drawings hasabase 2 to which is attached the frame 4:

carrying the driven or operating parts and the work guiding mechanism.As in the patent, this machine comprises oppositely disposed punches Pand oppositely disposed sets S arranged for reciprocation in bearings ina support or feed frame 6, with the anvil or die plate 8 also mounted insaid support or feed frame, arranged between the oppositely disposedpunches and eyelet setting dies. The feed frame and the devices carriedthereby extend at an angle of 45 to the vertical. The clamping membersor presser feet 10. are arranged to engage the work on the oppositesides of the guide plate 12, smoothing and guiding it to the settingdies.

In presenting the work to the machine punch the presser feet 10 yieldaway from the guide plate 8 allowing the opposite quarters of a shoe tobe drawn over the opposite sides of the guide plate 12 with their edgesagainst the edge guide 14: mounted on said guide plate. The machine isthen set in. operation whereupon the punches first advance and v0 holesin opposite sides of the upper in alinement with each other, then thefeed frame 6 rises to b ing the sets into the position previouslyoccupied by the punches and eyelets are presented to the sets S whichinsert and clench such eyelets in the holes in the work. After the setshave clenched the eyelets in the work they are released slightly butstill held in en gagement with the eyelets, and then the feed frame 6 ismoved laterally to feed the materials the desired distance between twosuccessive eyelet holes, the feed frame then makes its return or backfeed movement bringing the punches back to their original positions andthe operations are repeated.

In the accompanying drawings the actuat ing cams and mechanism forraising and swinging the feed frame 6 and the cams for actuating the setand punch operating levers 16'are omitted since they form no part of thepresent i vention but are similar to the corresponding parts shown inTat entllo. 934,066 to which reference may had.

The operating levers 16 are actuated by cams to impart the workingpressure to the punches P or to the setting dies 5 according as one orthe other of these devices are brought into operative position by thefeed frame 6. The punches P are each arovided with a forked projection18 which the outer end of a lever 20 pivoted on the frame 6 by the pin22. Each of the lovers 20 is provided with a rearwardly extending arm 24and extending between the arms 2%- and having a swiveled connectiontherewith is a tension spring 26 which tends always to l.

raise the levers 20 for retracting the punches.

The setting dies S are each provided with a recessed projection or block28 adapted to extend upwardly and rearwardly to clear the arms 3 of thelevers 30 and are so disposed as to allow the springs 36 and to extendin a parallel relation along one side of the feed frame 6 where theircondition may be readily observed by the operator and the springs easilyrenewed if not operating satisfactorily.

The guide plate 12 is 'slidingly mounted upon a fixed part of the frameand carries upon the position of the edge of the work with relation tothe setting devices, the

rearwardly. In order that the operator may conveniently move the gagesrearwardly prior to the introduction of each new piece of work forsetting the lowermost eyelets with a wider spread than the othereyelets, the guide plate 12 is provided with an eye 44 to which isconnectedone end of a flexi- The chain is guided over a guide-pulley .46on the frame 4 and is attached to the upper end of a treadle rod 48extending preferably to the heel end of the starting treadle (not shown)by which the guide plate 12, presser feet 10 and edge gages 14 may beshifted rearwardly. The guide plate 12 with the work clamped to it ismoved forwardly to its normal position and limited in its motion by thepinion 42, which constitutes part of an automatic device for moving theguide plate forwardly, after the first or lowermost pair of eyelets havebeen set, said automatic mechanism being fully described in Patent No.934,066 above mentioned.

The anvil plate 8 carries the cutting block 50 and the upsetting dies 52cooperating respectively with the punches P and the sets S. In order toprevent loose portions of the work from getting caught between theworkrest 13, which extendslaterally from the guide'plate, and the lowerend of the anvil plate 8, a guard plate 54 is mounted on the anvil plateand arranged to slide freely in a slot formed in the work rest 13.Preferably the shank 55 of the guard plate 54 may be utilized to retainthe cutting block 50 and the upsetting dies 52 within the anvil plate 8by being extended through a transverse bore formed in these members. Asshown in Fig. 2 the upper end of the shank is notched and the guardplate held in position by a locking screw set in the anvil plate. lVhenthe guide plate 12 is shifted rearwardly by the treadle through thechain 45 the work rest 13 slides upon the guard plate 54 to a positionnearer the anvil plate 8 than normally but is moved back to its normalposition at the end of the first cycle of the machine by the pinion 42.The operation of the. anvil plate is, of course, unaffected by theshifting of the guide plate. During the feeding operation the guardplate slides toward the left between the sides of the work rest 13.
